Because nobody cares, personal opinion. Do you have a study on the Pope's favorite color? (Red btw) Lutherans care what the Bible says about Mary.
Muslims must care even MORE!!
And remember Mary in the Book, when she withdrew from her family to an eastern place. And she veiled herself from them. Then We [God] sent unto her Our Spirit [the angel Gabriel], and it assumed for her the likeness of a perfect man. She said, "I seek refuge from thee in the Compassionate [i.e., God], if you are reverent!" He said, "I am but a messenger of thy Lord, to bestow upon thee a pure boy."
She said, "How shall I have a boy when no man has touched me, nor have I been unchaste?" He said, "Thus shall it be. Thy Lord says, It is easy for Me." And [it is thus] that We might make him a sign unto mankind, and a mercy from Us. And it is a matter decreed.
So she conceived him and withdrew with him to a place far off. And the pangs of childbirth drove her to the trunk of a date palm. She said, "Would that I had died before this and was a thing forgotten, utterly forgotten!" So he called out to her from below her, "Grieve not! Thy Lord has placed a rivulet beneath thee. And shake toward thyself the trunk of the date palm; fresh, ripe dates shall fall upon thee. So eat and drink and cool thine eye. And if thou seest any human being, say, Verily I have vowed a fast unto the Compassionate, so I shall not speak this day to any man."
Then she came with him [the infant Jesus] unto her people, carrying him. They said, "O Mary! Thou hast brought an amazing thing! O sister of Aaron! Thy father was not an evil man, nor was thy mother unchaste." Then she pointed to him [Jesus]. They said, "How shall we speak to one who is yet a child in the cradle?"
He [Jesus] said, "Truly I am a servant of God. He has given me the Book and made me a prophet. He has made me blessed wheresoever I may be, and has enjoined upon me prayer and almsgiving so long as I live, and [has made me] dutiful toward my mother. And He has not made me domineering, wretched. Peace be upon me the day I was born, the day I die, and the day I am raised alive!"
